  • This dataset contains water quality data from the inputs and outputs of eight reservoirs located in southeastern New Hampshire and northeastern Massachusetts. Samples were filtered in the field using Whatman GF/F filters with a nominal pore size of 0.7 µm and stored on ice until returned to the lab where they were frozen until analysis. Samples were analyzed for anions (NO3-, Cl-, SO4-, Br-) via ion chromatography on a Dionex Ion Chromatograph; NH4+ using a colorimetric method on a SmartChem Chemistry Analyzer; and total dissolved nitrogen (TDN) and dissolved organic carbon (DOC) via high-temperature oxidation on a Shimadzu TOC-V. DON was calculated as the difference between TDN and DIN (NO3- + NH4+).

    Samples correspond with individual sample names. Site (n = 8) indicate which reservoir each sample belongs to. Location indicates whether a sample was collected at the outflow or inflow ("UP", for reservoirs with one inflow) or "UP_1", "UP_2", or "UP_3" for sites with up to three inflows. CArea.km2 is the upstream drainage area estimated from the reservoir outflow while SArea.km2 is the surface area of each reservoir calculated via NHD+ polygons in GIS software. Temp.C is water temperature at the reservoir outflow on the day of sample collection while Discharge.m3s is the daily discharge scaled to the reservoir outflow from the nearest USGS gaging station. DIN.mgL, DON.mgL, and TDN.mgL are concentrations of dissolved inorganic nitrogen, dissolved organic nitrogen, and total dissolved nitrogen, respectively, in mg/L.
